Problems solved by technology

[0003] In order to provide such side flaps, there is known a method of making the side sheet material protrude to the outside of the main body of the absorber and trimming the remaining part to make side flaps. However, there is a problem that a lot of material is wasted due to trimming.

change example 1

[0058] refer to Figure 4 to Figure 7 A method for manufacturing an absorbent article according to Modification 1 of the present invention will be described. Next, the manufacturing method of the absorbent article according to Modification 1 of the present invention will be described focusing on differences from the manufacturing method of the absorbent article according to the first embodiment of the present invention.

[0059] In the manufacturing method of the absorbent article according to this modified example 1, in step S12, the both side edge parts 41a, 41b of the continuous body 120 of a flap are folded back several times on a flap line.

[0060] For example, if Figure 4 As shown in (a), in step S12, on the airfoil assembly line, when the both side edges 41a, 41b of the continuum 120 of the airfoil are folded back twice, as Figure 5 As shown in (a), the engaging members 31a and 31b are in an upward state. Therefore, since the engaging members 31a, 31b cannot be lo...

[0065] refer to Figure 8 A method for manufacturing an absorbent article according to Modification 2 of the present invention will be described. Next, the manufacturing method of the absorbent article according to Modification 2 of the present invention will be described focusing on differences from the manufacturing method of the absorbent article according to the first embodiment of the present invention.

[0066] First, the steps performed on the airfoil line will be described.

[0067] In step S11, in the continuous body 120 of elongated airfoils continuously conveyed on the airfoil line, on both sides of the center line C along the MD direction of the airfoil line, fittings that can fit into a predetermined area are arranged. Members 32a, 32b.

[0068] Specifically, in the fin continuum 120 , the engagement members 32 a , 32 b are arranged at predetermined length intervals on both sides of the vicinity of the centerline C along the MD direction of the fin line.

Abstract

Provided is a manufacturing method for absorbent products that has a process for placing on connected flaps (120) on flap line fastening members (30a, 30b) that are fastenable to prescribed areas on both sides of a center line (C) that is parallel to the MD-direction of the flap line, a process for folding over both edges of the connected flaps (120) toward the center line (C) along the MD-direction on the flap line, a process for forming flaps (20) by cutting the connected flaps (120) along the CD-direction on the flap line, and a process for placing the flaps (20) at prescribed intervals on connected absorbent products (110) on the main body line so that the center line (C) is in the MD-direction.

Description

technical field [0001] The present invention relates to a method for manufacturing an absorbent article having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent core body interposed between the top sheet and the back sheet, and an absorbent article manufacturing apparatus. Background technique [0002] In general, in an open diaper, it is necessary to provide side flaps (extrusion parts) that protrude outward from the absorbent core main body in order to facilitate wearing on the body. [0003] In order to provide such side flaps, it is known to protrude the side sheet material to the outside of the main body of the absorber and trim the remaining part to make side flaps. However, there is a problem that much material is wasted due to trimming. [0004] In order to solve such a problem, the manufacturing method of the diaper described in patent document 1 is known. The manufacturing method of such a diaper has the following steps. [0005] (1)...
